Abstract
Azoospermia is defined as the complete absence of sperm in the ejaculate even after centrifugation. With a prevalence of 1 % among the general male population and 10–15 % among infertile men, it can be classified in two large groups: obstructive and non-obstructive azoospermia (OA and NOA). The first is caused by an obstruction in the seminal tract (epididymis, vas, ejaculatory ducts), and the latter is due to impaired sperm production by the testis because of congenital maldevelopment and genetic, hormonal and acquired conditions. Diagnostic workup of azoospermia includes personal and familiar history, clinical evaluation, hormonal and semen biochemical assessment, scrotal and distal seminal tract transrectal ultrasounds and invasive investigations such as testicular fine needle aspiration, open biopsy and, in selected cases, vasography. OA can be treated by surgical recanalization of the seminal tract or sperm retrieval for ART. NOA treatment is represented by sperm retrieval for ART. Only the rare cases of hypogonadotropic hypogonadism might benefit from a medical treatment. MicroTESE has recently been proposed as an optimal method for sperm retrieval in NOA, and we describe a novel stepwise approach of this technique to reduce invasivity.
